Cascade Casing Spacers
The Cascade Casing Spacer system replaces
the old method of banding wooden skids to the carrier pipe
with steel straps.
Compare Cascade’s method with the obsolete one.
In addition to the typical design, Cascade has also
developed designs for:
·
Placing multiple carriers within one casing
·
Positioning thermally insulated pipe without
damage to insulation
·
Centering small carriers within large casings
·
Positioning gravity sewer to on grade requirements
